I was serious earlier.  As perhaps gross as it sounds, what ever the glycerinated ingredients are in personal lubricant, they add a whole new dimension to bubbles.  I don't know if it is the grapefruit seed extract, or polyethylene oxide, but the resultant bubbles can be huge.  The local bubble master from Marin has taken bubbles to a whole other level.  Though he didn't reveal the amount.  It's basically the same recipe as below with the addition of secrete ingredient, 1/8 to 1/4 cup for starters.  The results were impressive. It's the water soluble condom safe stuff, recommended by health professionals.
